I am using jio sim for the internet becuse it give free internet to all but it’s internet speed is very slow but now it give very improvment in his internet speed. Some months before I my house it’speed is 100kbps to 1mb but now it give 1mbps to 6mbps so it is big improvment. I am happy with this. You can buy jio sim because it after some months it give best quality of network and also give very much exiting offers for us.
